rmmount - removable media mounter for CD-ROM and floppy


/usr/sbin/rmmount [ -D ]


The rmmount utility is a removable media mounter that is executed by Volume Management whenever a CD-ROM or floppy is inserted. The Volume Management daemon, vold(1M), manages CD-ROM and floppy devices. rmmount can also be called by using volrmmount(1). Upon insertion, rmmount determines what type of file system (if any) is on the media. If a file system is present, rmmount mounts the file system in one of the following loca- tions: Mount Location State of Media /floppy/floppy0 symbolic link to mounted floppy in local floppy drive /floppy/floppy_name mounted named floppy /floppy/unnamed_floppy mounted unnamed floppy /cdrom/cdrom0 symbolic link to mounted CD-ROM in local CD-ROM drive /cdrom/CD-ROM_name mounted named CD-ROM /cdrom/CD-ROM_name/partition mounted named CD-ROM with partitioned file system /cdrom/unnamed_cdrom mounted unnamed CD-ROM If the media is read-only (either CD-ROM or floppy with write-protect tab set), the file system is mounted read- only. If a file system is not identified, rmmount does not mount a file system. See the System Administration Guide, Volume 1 for more information on the location of CD-ROM and floppy media without file systems. Also see volfs(7FS).

If the file system is "dirty," fsck -p (see fsck(1M)) is run in an attempt to clean it. If fsck fails, the file system is mounted read- only. After the mount is complete, "actions" associated with the media type are executed. These actions allow for the notifi- cation to other programs that new media are available. These actions are shared objects and are described in the configuration file, /etc/rmmount.conf. Actions are executed in the order in which they appear in the configuration file. The action function can return either 1 or 0. If it returns 0, no further actions will be executed. This allows the function to control which applica- tions are executed. In order to execute an action, rmmount performs a dlopen(3DL) on the shared object and calls the action func- tion defined within it. The definition of the interface to actions can be found in /usr/include/rmmount.h. File systems mounted by rmmount are always mounted with the nosuid flag set, thereby disabling set-uid programs and access to block or character devices in that file system. Upon ejection, rmmount unmounts mounted file systems and executes actions associated with the media type. If a file system is "busy" (that is, it contains the current working directory of a live process), the ejection will fail.
